Following several campaigns against neighboring worlds, the Narn began relying more and more on their larger T'Loth cruisers for power projection. This left the older T'Rakk Frigates to fill in the gaps, providing support for the valuable frigates.

The T'Dok Escort Carrier is a modificaiton of the T'Rakk designed to provide Narn fleets with additional anti-fighter support. Providing excellent Twin Array coverage, as well as a flight of Goriths, the T'Dok is meant to escort T'Loths into battle and protect them from enemy fighters at all costs.

The T'Dok proved to be a cheap hull, and an effective on given the cost. Despite this the T'Dok was largley replaced by the growing numbers of T'Loth and newer Narn ship hulls being produced by the Regime.
